To all whom it may concern:

Be it known that I, JOHN B. ALBERs, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Metal-Saving Machines, of which the following is a specification.

My invention relates to that class of metalsaving machines in which the metal is dis solved by chemicals; and the object thereof is to produce a machine in which the metal will be extracted from the pulp in a more expeditious manner than can be accomplished by the machines in common use for that purpose. I accomplish this object by the mechanism described herein and illustrated in the accompanying drawings, in which Figure 1 is a vertical section on the line 1 1 of Fig. 4. Figs. 2 and 3 are horizontal sections on the lines 2 and 3, respectively, of Fig. 1. Fig. 4 is a vertical section on the line 4 4 of Fi 1. Figs. 5 to -8 are views illustrating detai s of different parts of the device hereinafter described.

In the drawin s, 10 is the building, which incloses the wor ring parts of my machine. On the floor of the building is a mixingtrough 11, in which is rotatively mounted a shaft 12, provided with a pulley 13, to which power is applied to rotate the shaft. Secured to the end of shaft 12 nearest the driving-pulley are the mixing-bars l4, and at the other end of saidshaft is a conveyer-screw 15, which forces the pulp out of the mixingtrough after it has been agitated by the mixing-bars. The pulp is forced by the conveyer-screw 15 into a receiving-chamber 16 and is carried out of said chamber by buckets 17, which are carried by sprocket-chains 18 and 19, forming an elevator. These chains pass over and are driven by sprocket-wheels 20 and 21, which are mounted upon drivingshaft 22, on which is mounted driving-pulley 23, to which power is applied to drive the shaft. These chains also pass over the idler or direction-changing sprocket-wheels 24 and 25, located above sprockets 20 and 21, and also over sprocket-wheels 26, which guide the other side of the conveyer. The pulp is deposited by buckets 17 upon the top covering .27 of the aerating-tanks 28 and 29. In this top covering are hinged doors 30 and 31.

When door 30 is opened, the pulp will pass into tank 28, and when door 31 is open the plulpdwill pass into tank 29, door 30 being 0 ose Q Extending transversely the aerating-tanks are a large number of triangular-shaped agitances also, preferably extending transversely the aerating-tanks, are air-distributing conduits 33, which are also preferably triangular in shape, with their apexes projected toward the top of the tanks, and the alternate rows are preferably staggered for the same reason that the agitating-bars are staggered. In the bottom of the air-distributing conduits are the air-ports 34, through which the air passes into the tanks. Below the agitatingbars are the filtering-frames, ofwhich there are preferably one on each side and two in the center, as best shown in Fig. 4, although there may be more or less of these frames, accordingto the capacity of the machine. These filtering-frames are composed of slats 35, which are covered with canvas or other cloth 36. v

In Fig. 5 I have shown the form of the slats that are used next to the outside walls, and in Fig. 6 I have shown the form of the slats that are used in the center. The filteringframes are preferably more widely separated at the top than at the bottom, as best shown in Fig. 4, as thereby a somewhat greater filtering capacity is provided in a given space than if vertical, and they rest upon supportingbase-frames 37. Below these base-frames are the combined adjusting and moistening' valves 38, which'are hollow and are provided at one end with a hollow trunnion 39, through which water or chemical solution may be admitted into the interior, if desired. At the other end, trunnion 40 is provided with an operating-handle 41, by means of which the valve may be turned partially or wholly across the opening between the base-frames 37. Below these valves is a screw conveyer 42, which forces all material passing the valves into passage-way or channel 43, through the bottom of which passes an elevator composed of buckets 44 and sprocketchains 45, which are driven by sprocketwheels 46, mounted on shaft 47, which last shaft is provided with driving-pulley 48, 550

which power is applied. These buckets carry the material to the top of the building and deposit the same upon deflector 49 If the material is so far treated that it is only necessary that it should be passed through the final aerating-tank 50, the deflector is turned, as shown in full lines in Fig. 4, to carry the material into this tank. If the pulp requires a greater amount of treatment than canbe obtained by passing it through the final aerating-tank to extract all of its values, the deflector is turned, as shownin dotted lines in Fig. 4;, so as to carry the material and deposit it the aerating tanksZS r 2 as des ed- As shown Fig- 4, the final aerating-tank is at a much higher elev tiQIl than the first aeratingfianks So that when the material is forced out of the same by a screw conveyor 51 it is carried therefrom by suitable means to the dump. (Not shown.)

' It i l e un ers ood t h or c ushed to the required degree of fineness, is fed into the mixing-trough with the required amount of solution for the proper treatment of the lore, and hat it is elevated to and dep s ed into the top of the aerating;tanks, and that ai unde th requir degree of compres ion is furnished to compartment 52 through pipe 60 from a suitable source of supply, (not shown,) and that as the pulp passes down.

through the aerating-tanks a constant supply of compresse ai is for ed h ough t e me. at a m ny ifferent l ve s a m y d ed, and that the pulp is subjected to an alternate compr sion and e pa ng p oc s nd s alternate y sub i ided t i erent points as it passes downwardly through the aerating tan s, and tha when it passes be ween the filte ingr mes a very con i erab po on of the liquid passes through the canvas and into a oha ine .3 at the end o the lte ng: rames of the a a inganks 28 a d rom which it is elevate by pump 4. h ough P pe 55 into a settling-tank 56. From the final aerating-tank theliquid, is elevated by pump 57 through'pipe 58. into the settling-tank 5 6. The final aerating-tank is constructed in all particulars like aerating-tanks 28 and 29, ex cept that it is not as long and terminates at a higher elevation, preferably, so as to provide convenient means for handling the refuse material. The air-conduits are connected te an air-compa e 9,, Which is supplied With air from pipe 60 through ports 61 therein.

It will be seen that in the operatiQI Qf'my machine t s esira le fi st to 1 up the aerating-tanks 28 and 29 to, the top and to regulate the flow Of the material thereafter therethroug y ves 8., s tha a a ge percentage o the l qu filters ou th ough the. canvas offh filtering-flame.

ing-frames, by rotating valves 38 so as to bring ports 38 so that they open into the space between the. base-frames 37, water or solution can be forced through the valves and out ofthe ports to moisten the material, so that it will readily flow through the conveyorscrew 42. Should the material get clogged in the screw, the valves can-be rotated so as to bring the parts to bear thereon and the material can be washed out of the conveyorscrews by forcing water or solution through the valves.
